0.3 m/s is the speed of a wave with a wavelength of 3 m and a frequency of 0.1 HZ.
Explanation:
Speed of wave is related to both wavelength and frequency of waves. The wavelength is the displacement between the respective points of two adjacent waves. Wave frequency is the waves number that travels through a fixed points at given time. Hence, the equation that shows how three factors are related as below,
[tex]\text { Wave speed }=\text { Wavelength } \times \text { Wave frequency }[/tex]
This comparison measures the wavelength in meters and frequency in hertz (Hz) or the number of waves per second. Hence, the wave speed expressed in meters per second (the S.I unit of speed).
Here, given wavelength = 3 m and frequency = 0.1 Hz. So, the wave speed is calculates as
[tex]\text { Wave speed }=3 \times 0.1=0.3 \mathrm{m} / \mathrm{s}[/tex]
